Indian Power and Energy Sector

The Shivasamudram hydroelectric power station, commissioned in 1902 on the Kaveri River in Karnataka, was the first major hydroelectric power station in India.

Manikaran, located in the Parvati Valley of Himachal Pradesh, is well known for its hot springs and is the site of a geothermal energy pilot plant in India.

Singrauli, Ramagundam, and Rihand are all major sites for large-scale thermal power stations in India, operated by NTPC.

ONGC discovered India's first shale gas reserves in the Raniganj coalfield area of West Bengal.

Uranium is a radioactive metal primarily used as fuel in nuclear power reactors to generate electricity.

In rural India, traditional sources like firewood, cow dung cakes, and agricultural waste remain the primary energy sources for cooking and heating.

Solar energy is widely considered the most promising non-conventional source in India due to the country's high solar insolation levels.

Based on standard economic data for India, gas-based power accounts for a relatively small percentage of total installed capacity, typically around 9%.

Thermal energy (primarily coal-based) constitutes the largest share of India's power capacity, though the specific percentage varies by year; 27% is likely a dated or specific source figure.

Nuclear energy contributes a small portion to India's total electricity mix, consistently reported around 2-3%.

Hydel energy's contribution to India's total generation capacity is typically cited around 15%.

Energy sources in India are broadly classified into commercial and non-commercial categories based on their availability and marketability. Commercial sources are bought and sold in the market, while non-commercial sources are typically gathered.

Power generation in India is a concurrent subject where the Central government, State governments, and private sector companies are all permitted to participate to meet energy demands.

Thermal power plants, primarily coal-based, account for the largest share of electricity generation in India, making it the bulk of commercial energy.
